Answer:

2.9 g of water are produced by 9.6 g of ammonium perchlorate

Note: The question is incomplete. The complete question is given below:

Ammonium perchlorate (NH₄ClO₄) is the solid rocket fuel used by the U.S. Space Shuttle. It reacts with itself to produce nitrogen gas (N₂) , chlorine gas (Cl₂), oxygen gas (O₂), water (H₂O) , and a great deal of energy. What mass of water is produced by the reaction of 9.6 g of ammonium perchlorate? Be sure your answer has the correct number of significant digits.

Explanation:

The reaction of ammonium perchlorate (NH₄ClO₄) to produce nitrogen gas (N₂) , chlorine gas (Cl₂), oxygen gas (O₂), water (H₂O) is shown in the balanced chemical equation given below:

2 NH₄ClO₄ → N₂ + Cl₂ + 2 O₂ + 4 H₂O

From the equation, 2 moles of ammonium perchlorate produces 4 moles of water, i.e. mole ratio of NH₄ClO₄ to H₂O = 2 : 4 = 1 : 2

molar mass of ammonium perchlorate, NH₄ClO₄ = (14 + 4 * 1 + 35.5 +16 * 4) = 117.5

molar mass of water, H₂O = (2 * 1 + 16) = 18.0 g

mass of water produced = moles of ammonium perchlorate * 2 * molar mass of water

moles of perchlorate = mass / molar mass = 9.6/117.5

mass of water produced = 9.6/117.5 * 2 * 18.0 g = 2.94 g of water

Therefore, 2.9 g of water are produced by 9.6 g of ammonium perchlorate

Answer : As I understand this is question of matching the correct pairs.
So here are the correct pairs.

1) The attraction between molecules at the surface of a liquid column

---->Surface tension

Surface tension is a phenomenon observed at the surface film of a liquid which is usually caused by the attraction of the particles on the surface layer by the bulk moiety of the liquid, and which tends to minimize its surface area.

2) The energy of motion

----> Kinetic energy

Kinetic energy is the energy which is possessed by an object due to motion.

3) The movement of liquids through the spaces of materials

----> Capillary action

Capillary action is defined as the ability of any liquid to flow through the narrow spaces without any of the assistance, or even in opposition to, external force like gravitational force.

4) The overall movement of suspended or dissolved particles resulting from the random movements of individual particles

----> Diffusion

Diffusion in liquids can be defined as the random movement of particles which are dissolved or are in suspended state in liquid.

5) Attraction of one particle in a material for another

----> Cohesion

Cohesion is defined as the attraction between two different particles in a state of matter

6) The attraction between unlike substances

----> Adhesion

Adhesion is a property of attraction between two unlike substances.

7) A measure oof the resistance of a liquid to flow

----> Viscosity

Viscosity is the term used to define as the resistivity of liquid to flow.

The carbocation stabilized by resonance structure and thereby lowers the energy of the carbocation, hydrogen will add to the carbon in the double bond that produces delocalization of electrons.

<h3>What is carbocation?</h3>

A carbocation is a molecule in which a carbon atom has a positive charge and three bonds.

In general, electrons are stabilized by delocalization. The stabilization energy engendered by delocalization over more than two atoms is called the resonance stabilization energy or simply the resonance energy. The greater the extent of electron delocalization the greater the resonance stabilization.
